I was laughing the whole way through this. I loved the tone it was written in. My favorite part was this:
'And if he wakes up in time to hear the boy talking to the dragon, well, no one would believe him anyway. Not that it matters - after all, he just told the dragon to go away, so it's all good in the end, right? Right?'
Hilarious :D

Great story, I like the recurrence of twitching as a method of avoidance. But the following is one of the fanfics I've always wanted to see: "The day that Arthur is crowned is the day that Merlin steps forward and reveals he uses magic, has been using magic, and fully intends to keep on using magic."

Me chapter 1 . 3/24/2014

Just to say this is great and I'm happy that I'm not the only one who wondered how he managed to survive every freaking attack etc. I like him in the show, so at first I was worried he'd die... but then I came to realise that he may live forever...

Oh this is really fun. I like how you went through Leon's history to show what he'd thought about magic and his situation. And how he realized that he'd known it all along. And wanted to keep it. The descriptions are great and I loved how Merlin came up to him and asked it he knew and wanted to keep it. Which of course he did, because... hahaha... that last section! XD
